Woon-SHAPING MACHINE.

Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed August 28, 1918. Serial No. 251,814.

To all whom t may concern:

Be it known that we, GEORGE W. DUVALL and NORMAN H. BEEBE, citizens of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Wood-Shaping Machines, of which the following is a specification.

Our invention relates to an improvement in wood shaping machines.

The primary object of this invention is to provide a machine for shaping the ends of broom handles, although other similar work may be performed by this device.

In the accompanying drawings Figure 1 is a view in perspective of the complete device;

Fig. 2 is a side elevation of the sliding vise, showing the vise hook up ready to receive a handle;

Fig. 3 is a view in perspective of the saw frame and feed wheel frame;

Fig. 4 is a View in perspective of handle holding mechanism;

Figs. 5 and 6 show the end of a broom handle, after having been operated on by the machine;

Fig. 7 shows in perspective the saw shaft, driving sheave Wheel and saw driving belt wheel.

No. 1 is the column or main frame of the machine.

Nos. 2 and 3 are the cutter-shaft frames.

The cutter-heads 4 and 5 are mounted on the shafts 6 and 7. The driving-pulleys 8 and 9 are also mounted on the shafts 6 and 7. The shafts 6 and 7 revolve in bearings which are a part of frames 2 and 3. The frames 2 and 3 are adjustably held in alinement by the key 10. The frames 2 and 3 are attached to the column by bolts. These bolts pass through slotted holes a. in the frames, thus permitting the frames to be adjusted vertically on the column. Knives such as are shown by 11, 12 and 13, are attached to cutter-heads 4 and 5. The cutting edge of these knives may be of any desired shape.

14 is the track on which the handle vise 15 slides. This vise grips the handle 16 and enables the operator to push the handle for ward, passing the same in a straight line between the rapidly revolving knives. It will be seen that one or both sides of the handle may be operated upon at the same time. It is also apparent that as the cutters are vertically adjustable, a greater or less amount may be cut from either side of the handle.

The track 14 is attached to column 1 by the bracket 17. After the handle 16 has passed between the cutters, it comes in contact with the feed wheel 18 above it and the curved tracks 19 below it. The feed-wheel revolves in the direction indicated by the arrow of Fig. 1. Just as the handle 16 touches the feed wheel, the operator raises the vise lever 20, as shown in Fig. 2. This releases the handle, allowing same to roll along the tracks 19. To support the weight of the handle, a curved track 21 is provided. This latter track is preferably made of rubber, and is attached, as shown, to track 14.

Feed-wheel 18 is secured to shaft 22, which shaft revolves in bearings 23 and 24. A worm-wheel 25 is located between bearings 23 and 24, being attached to shaft 22. The worm 26 meshes with and imparts motion to wheel 25, and by means of shaft 22 revolves feed wheel 18. The worm 26 is mounted on shaft 27. This shaft revolves in bearings 28 and 29. The sheave wheel 30 is secured to the upper end of shaft 27.

A saw 31 is attached to a shaft 32 (see Fig. 7) revolving in the bearings 33 (see Fig. 3). This saw may be composed of sections placed side by side. As the handle 16 rolls along between the wheel 18 and track 19, the saw produces the annular groove o and cuts the handle to size at either side of groove, as shown in Figs. 5 and 6. The flat portions c of the handle shown in Figs. 5 and 6 were produced by the cutters 11, 12 and 13.

Mounted on the saw shaft 32 is the saw driving pulley 34. Attached to the same shaft and located between pulley 34 and bearing 33 is a sheave wheel 35. This sheave-wheel imparts motion to the round belt 36. This belt in turn imparts motion to sheave 30 (see Figs. 1 and 7).

As the broom handles are not perfectly round and vary in size, it is essential to hold them with a spring pressure. Therefore, the tracks 19 are attached to the spring 37. The spring in turn is secured to springholder 38. The spring-holder 38 is attached to column 1. In an unrestrained position the spring 37 would hold the tracks 19 so near the wheel 18 that it would be difficult to start a handle between the wheel and track. For this reason, the spring is drawn downward by the bolt 39 and nut 39a.

The feed wheel frame is bolted to the saw frame by bolts cl, which pass through slotted vholes e, thus permitting an independent vertical adjustment of the feed wheel frame. yThis is necessary as the saws vary in diameter from sharpening and may cut too deep or too shallow.

Attention is called to the construction and operation of the handle vise 15. In Fig.' 1 a broom-handle is shown held by the vise. The operator grips both vise levers tightly, thereby causing the hook 40 to force the Vhandle firmly in the groove of the jaw 45 of the vise. Fig. 2 shows the position of the vhandle 2O and hook 40 when it is desired to vrelease or insert a handle. The staple 41 compels the hook 40 to assume the position shown in Fig. 1 when the lever 20 is lowered. A handle gage 42 is provided, being attached to ro-d 43. This rod is secured to bracket 17. The gage makes it possible to cut all handles the same length. Belts 46 and 47 passed over pulleys 8, 9 and 34 drive the shafts 6, 7 and 32.

We claim:

1. The combination with cutters and a saw, of a slidably mounted vise for holding the article to be fashioned, and means for guiding the vise and article held successively to the cutters and the saw, and means for receiving the article from the vise and rotatably feeding it past the saw.

2. The combination with cutters and a saw, of a slidably. mounted vise for holding the article to be fashioned, means for guiding the vise and article held successively to the cutters and the saw, and a toothed adjust'ably supported track between which and the saw the article being fashioned passes.

3. The combination with cutters, a saw, a feed-wheel adjacent to the saw, and a curved track between which and the saw and feedwheel the article being fashioned passes, o-f a slidably mounted vise constructed and adapted to grip the article to be fashioned, and means for guiding the vise whereby to conduct the article being treated between the cutters and thence between the feed-wheel and the curved track in position to be operated upon by the saw.

4. The-combination with cutters, a saw, a feed-wheel adjacent to thev saw, and a curved.

track between which and the saw and feedwheel the article being fashioned passes, of a slidably mounted vise constructed and adapted to grip the article to be fashioned, means for. guiding the vise whereby to con-- duct the article being treated between the cutters and thence between the feed-wheel and the curved track in position to be operated upon by the saw, means for adjusting the curved track, and an additional curved track of yielding material in position to support the article while passing in the path of the saw.

5. The combination with a curved toothed track, and a toothed feed wheel cooperating with the toothed track to positively roll the article being operated upon between them, of a saw concentric with the feed wheel and independently actuated for making a circumferential cut upon the surface of the article tobe fashioned while it is being rolled between the toothed track and the periphery of the feed-wheel.
